🎮 Task Switching Test: Measure Your Switch Cost

💡 How to play — A coloured digit appears and the rule above it tells you what to judge. Under the number rule you say whether the digit is over or under 5; under the colour rule you say whether it is red or blue. The rule keeps changing without warning, and the trials right after a change are the ones that slow everybody down — that lag is the switch cost. You have 30 seconds, and because there are only two buttons, a wrong answer subtracts exactly what a right one would have added.
